meInvoice Web — Invoice Download Trial

Trial harness built from the reverse-engineered Android app (v58.0.1, Flutter). It tries the endpoints found in the app against MISA's backend, shows every raw response, and downloads invoice PDF/XML files to your browser. HTTP verbs and parameters were not provable from the binary alone — this tool tries the candidates in order and reports which one actually works, so you can confirm the real API shape with your own account.

Credentials: anything you type (MISA ID password, tokens) lives only in this browser tab's memory (sessionStorage) and is sent only to MISA's servers via this site's proxy. Nothing is stored on the server, nothing is logged, and closing the tab clears it. Use the Clear session button when done. Prefer the Paste token mode if you already have a token — it avoids typing your password here at all.

1 · Settings

Host and company scope. Dates default to yesterday (the daily-download window).

2 · Sign in

Auth in the app: MISA ID → access token → meInvoice JWT. This step tries the candidate token endpoints in order and keeps the first token it finds.

Status: Not signed in

3 · List invoices

Tries the paging endpoints for the chosen family (POST with JSON body first, then GET) and renders the result. The raw response is shown in the log below.

4 · Download PDF / XML

For each listed invoice, tries the file-download candidates in order: /Handler/V3DownloadHandler.ashx, then /invoices/print-pdf, then /invoices/invoicefiles-trans. The handler's exact query parameters were not in the binary — edit the templates below if the first try fails; {refId}, {code}, {id} are replaced per invoice.

5 · Raw API tester

Try any endpoint from the spec directly. Useful for confirming a verb or a parameter the list/download steps guessed wrong.

Try: /v3system/appconfig (no login needed, checks the proxy), /v3sainvoice/paging, /v3invoice/code/preview.

Request log

Every attempt, in order, with status and a truncated body. Tokens are masked here.

Ready. Sign in first, then list invoices.
